Reproductive biology and behaviour of Enyalius lizards

Goal: Basically to analyze the reproductive biology and behaviour related to Enyalius lizards, in order to elucidate the reproductive cycle associated with morphological and ecological parameters of the species.

Methods: gonadal analyses, morphological measures, and ecological data associated with the reproductive cycle of each species

New paper (March/2020) on Enyalius boulengeri.

Enyalius boulengeri Etheridge, 1969 occurs in the Atlantic Forest, in the states of Espírito Santo and Minas Gerais, in southeastern Brazil (Costa and Bérnils, 2018), and its conservation status has not yet been assessed, since basic information on its biology is still scarce or non-existent in the literature. We here describe for the first time a copulation of E. boulengeri under natural conditions, in a protected area in the state of Espírito Santo. In addition, we discuss the courtship and copulation behaviours of some other Enyalius species.

Reproductive timing and fecundity in the Neotropical lizard Enyalius perditus (Squamata: Leiosauridae)

Enyalius perditus is a semi-arboreal lizard species whose reproduction is poorly known. Here, we combine information obtained from preserved and live specimens to describe the reproductive timing (vitellogenesis, gravid-ity, and egg-laying) and fecundity (clutch size, egg size, and relative clutch mass) in females of E. perditus. Female reproduction is remarkably seasonal and occurs in the warmer and wetter periods of the year. Secondary vitellogenesis occurs from mid to late spring, whereas gravidity and egg-laying occur in early summer. Mating appears to be synchronized with secondary vitellogenesis, indicating an associated reproductive cycle. We suggest that E. perditus females produce only a single clutch per reproductive season. Clutch size ranged from three to 11 eggs and was positively correlated with female body size. Finally, the relative clutch mass was high, a recurrent feature to "sit-and-wait" foragers.

Reproductive timing and fecundity in Neotropical lizard Enyalius perditus (Squamata: Leiosauridae), authored by Serena Najara Migliore, Henrique Braz, André Felipe Barreto-Lima, and Selma Maria Almeida Santos, has been accepted for publication in Acta Herpetologica and it will be part of the second issue of the 2017 (vol. 12), which is going to be published in December 2017 (online version).
